What if you are an idiot anyway
Intersecting lines are _____ coplanar.
Always
Points that lie on the same line.

True or False. If two lines intersect, then they intersect in exactly one point.
True

Coplanar
When to planes intersect do they intersect at a point, a line or a plane?
A line.
CRITICAL THINKING Is it possible for one point to be
in two different planes? Explain your reasoning.
Yes it is.
Right on the intersection of two planes.
It is possible for two angles to be adjacent, congruent, and complementary.
Explain
